Multiquip 48374-SK Service Kit MD80 Muffler with Isolators - OEM Replacement Part

This service kit provides a complete muffler assembly with isolators for the Multiquip MD80 ride-on power trowel, ensuring proper exhaust routing and vibration dampening for the Vanguard 61G200 V-Twin EFI engine. The muffler and isolator system is critical for reducing noise emissions while maintaining the MD80's guaranteed sound pressure level of 91 dB(A) at the operator station and sound power level of 121 dB(A) as specified per ISO standards. Damaged or deteriorating mufflers can lead to excessive noise, poor engine performance, and potential safety hazards from hot exhaust components.

The isolators in this kit are designed to minimize heat transfer and vibration from the exhaust system to the trowel frame, protecting surrounding components and maintaining operator comfort. Regular inspection of the muffler system is recommended, especially on machines operating in demanding finishing applications where the 40.0 hp engine runs at sustained high RPM. Replace when you notice excessive exhaust noise, visible damage to the muffler body, cracked or deteriorated isolator mounts, or exhaust leaks that could affect engine performance.
